Conventionally, in order to drain rainwater that accumulates on the roof of a building, etc., first, a drainage fitting is fitted into a drainage hole opened on the floor of the roof, and the end of a waterproof sheet spread on the floor of the roof is connected to the drainage fitting. The water that flows on the tarpaulin sheet can be drained from the drainage fitting. However, during use, the waterproof sheet came off and rainwater entered the gap between the sheet and the drainage fitting, flowing onto the concrete floor and causing rain leaks.

However, it was later improved, and as shown in Fig. 1, the lower part of a bolt B made of brass or the like is screwed into the upper surface of the cast iron body A of the drain collection device, and the bolt hole is inserted through the upper part of the body. Place the presser fitting C that has been installed, insert the bolt hole into the bolt B of the main body A, and tighten the nut N.
A device was devised in which the end portion of the waterproof sheet D was sandwiched between the main body A and the holding metal fitting C, but when using this device, the bolts B or The attachment part of the bolt B corroded and broke off or came off, making it insufficient to hold down the holding fitting C, and the waterproof seal D came off, causing rain to leak. Also bolt B
If the attachment part of the bolt B becomes corroded, it becomes impossible to replace the bolt B, and therefore the main body A itself must be replaced, which not only makes the replacement work difficult but also increases the replacement cost. It was hot.

In addition, a dust-proof cap S called a strainer was placed on the top of the presser metal fitting C to prevent the intrusion of dust, etc., but since it was not structured to be fixed simply by placing it, the dust-proof cap S When some kind of impact is applied to the cap S, the cap S moves and the flow outlet is exposed, making it difficult to achieve a dustproof effect.

The present invention uses a pressing member, a locking member, and a screw rod to press the holding metal fitting against the main body of the water collection device, without screwing a bolt onto the main body, and uses the screw rod to prevent dust. It is an object of the present invention to provide a water collecting and draining device which also fixes the cap and further has a gap between the main body and the presser fitting which allows filling of a sealing material or the like.

That is, the lower part of the locking member formed in a bifurcated shape is locked to the lower end of the pipe part of the main body of the water collection device, the lower part of the screw rod is hooked to the upper part of the locking member, and the upper part is extended upward.

The part corresponding to the intermediate steep slope 5 is not in close contact with the other, and a slight gap 10 is provided, and a flow outlet 11 is provided through the central part.

Reference numeral 12 denotes a pressing member for pressing the presser metal fitting 9 against the main body 3, which is formed by curving a metal band plate into an arc shape, and has a hole 14 in the center for loosely fitting the threaded rod 13. It is installed through. Incidentally, the screw rod 13 is threaded from a portion slightly below the pressing member 12 to an upper portion thereof, and a hook portion 15 is formed at the lower end portion. Reference numeral 16 denotes a locking member formed by bending a metal bar or strip into a chevron shape into a bifurcated shape, and has locking portions 17, 17 bent upwardly at both lower ends thereof. . Further, 18 is a drain pipe connected to the pipe portion 7 of the main body 3, 19 is a waterproof sheet, and 20 is a dustproof cap.

When installing the drain collection device of this example on the roof of a building, etc., the main body 3 is first fitted into the drain port 2 provided in the floor wall 1 of the roof. In this case, the shape of the drain port 2 is formed to match the shape of the bottom surface of the main body 3 so that the bottom surface of the main body 3 is in close contact with the bottom surface of the main body 3, as shown in FIG. or below.

Next, a waterproof sheet 19 is laid on the floor, and its ends are overlapped around the upper part of the main body 3. Next, the presser metal fitting 9 is placed on top of the main body 3, and the peripheral edge of the waterproof sheet 19 is sandwiched between the presser metal fitting 9 and the main body 3.

The locking member 16 is inserted into the tube portion 7 of the main body 3, and the locking portions 17 at the lower end of the locking member 16 are respectively locked in the notches 8 of the tube portion 7, and the lower hook portion 15 of the screw rod 13 is hooked to the top of the locking member 16. Next, the center hole 14 of the pressing member 12 is inserted into the screw rod 13 from above, the end of the pressing member 12 is placed in contact with the presser fitting 9, and the nut 21 screwed into the screw rod 13 is screwed into place. advance to press against the pressing member 12, and press the screw rod 1.

Next, the dustproof cap 20 is formed into a cap shape and has a large number of long openings, and a hole formed in the center thereof is inserted into the upper part of the screw rod 13, and the dustproof cap 20 is placed on the holding fitting 9. The dustproof cap 20 is fixed by screwing the nut 22 onto the screw rod 13. Also, main body 3
A sealing material is filled into the cavity 10 formed between the presser and the presser fitting 9.

When rainwater collects on the floor of the roof, the rainwater flows over the waterproof sheet 19 and reaches the drainage collection device, and the rainwater that enters the holding metal fitting 9 flows downward and flows through the pipe section 7 of the main body 3 through the drainage port 11. The water then flows down the drain pipe 18 and is drained.

The main body 3 and the presser fitting 9 are made of stainless steel plate,
In addition to light alloy plates, it is preferable to use brass plates or other materials, such as hard alloy resin, which have appropriate rigidity and have a smooth surface.

Although the pressing member 12 in this example is formed into an arc shape with the ends of the metal material extending in two directions, it may also have a cross shape with four extensions, or a shape extending in three or five directions. Further, the shape of the locking member 16 is not particularly limited, and the cutout 8 at the lower end of the tube portion 7 of the main body is not provided, so that the locking portion 17 of the locking member 16 is engaged with the lower edge of the tube portion 7. It may also be stopped.

Furthermore, by making the outer diameter of the upper end of the threaded portion of the threaded rod 13 smaller than the threaded inner diameter of the nut 21, it is also possible to loosely insert the nut 21 to the vicinity of the pressing member 12 before screwing it on. .

As mentioned above, the water collection device of the present invention installed on a rooftop etc. presses the presser metal fitting 9 that is in close contact with the upper part of the main body through the screw rod 13 connected to the locking member 16 fixed to the lower end of the main body. Since the pressure is applied, the bolts and bolt attachment parts installed in the main body will not be damaged or detached due to corrosion, which was the case in the past, and the waterproof sheet will be completely pressed, preventing the occurrence of rain leaks. This not only prevents problems, but also eliminates the need to replace the main body itself due to damage to bolt attachment parts.

Further, since the dustproof cap is also fastened to the screw rod with a nut, it will not move even if some impact force is applied to the dustproof cap, and the dustproof effect can be sufficiently improved.

Further, since a gap is provided between the main body and the holding fitting to be filled with a sealant or the like, the effect of preventing water leakage is further increased.
